我正在尝试使用 selenium 来测试我的 django 应用程序

运行以下命令后：

python3 manage.py test function_test(folder)

出现以下错误：

*Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/django/db/backends/base/base.py", line 130, in ensure_connection

我已经在我的主项目中安装了 hstore 并且我在 live_server_test_case 上运行测试，所以它不应该产生问题。

有没有一种方法可以在运行 selenium 代码之前跳过迁移，因为我已经提到在 setup() 函数中创建 hstore 类型，但我无法访问代码。

当你运行测试时，Django 会创建一个测试数据库。UsingLiveServerTestCase意味着有一个 Django 服务器可供测试使用（例如 Selenium），并不意味着它使用实时数据库。

听起来您需要创建一个迁移来安装 HStoreExtension。Django 测试运行器将运行迁移，防止错误。有关更多信息，请参阅文档或此问题。
